What percentage of total clients should be included for quality evaluation?

• A. At least 30%
• B. At most 10%
• C. Exactly 50%
• D. At least 20%

Answer: (A)

When evaluating quality, you need a sample size that is large enough to represent the variety seen in the client population. Including at least 30% of total clients provides a practical balance between accuracy and effort, increasing the likelihood that the assessment captures different groups, service types, and time periods. A smaller sample (like 10% or 20%) can miss important differences and lead to unreliable conclusions, while evaluating half of all clients isn’t usually necessary to get a solid picture. So, aiming for a minimum of 30% helps ensure the quality evaluation reflects overall performance and supports meaningful improvements.
